Answer: It can be attributed to three aspects: I. Varieties: There is not much difference in size between individual varieties of some varieties. These varieties are suitable for long-harvest cultivation. The results can reach 17, 18 or even 20 sets of fruit. Generally, such seeds are more expensive. Another common and popular variety is that each fruit is smaller than the previous one, that is, the smaller the fruit is, the more it goes up. These varieties are suitable for the cultivation of relatively short harvest period, generally 3 to 4 sets of fruit knots, after which must be steamed, usually 3 to 4 pieces of fruit per panicle. Second, the fertilizer: The lack of all kinds of elements necessary for plants will cause the fruit to become smaller, the lack of magnesium, manganese, boron may affect the size of the fruit. In addition, the improper application of fertilizers will also affect the size of the fruit, such as large amounts of ruminant feces but not a large amount of nitrogen will cause crop nitrogen deficiency. Excessive, frequent application of a large amount of diammonium, resulting in crop phosphorus poisoning, the fruit will become smaller. The correct application method of potash fertilizer is to chase the plants in stages. If they are put in once, the crops will be reduced in production. The same amount will be divided into three times (the first time is less), and the increase in production will be large. Excessive amounts of some elements, such as boron, can also make the fruit smaller. Third, the cultivation aspects: 1. No scaffolding, plant lodging; 2. The latter species did not go to the head; 3. Water shortages; 4. The soil is too stiff; 5. Auxin poisoning - This is the most common fruit of the greenhouse For smaller reasons (one flower per point, auxin accumulates a bit, and the fruits will be affected after three or four sets of fruit), it should be corrected with gibberellin once every three to four.
